Deep roots occur in

Options

A. Perennial nonsucculent xerophytes
B. Perennial succulent xerophytes
C. Annual xerophytes
D. Ephemeral xerophytes

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the type of plants that have deep roots. We need to identify which category of plants is characterized by having extensive root systems that penetrate deep into the soil.

2. **Identifying the Options**: The options provided are:
- Perennial non-succulent xerophytes
- Perennial succulent xerophytes
- Annual xerophytes
- Epiphytomal xerophytes

3. **Defining Xerophytes**: Xerophytes are plants that are adapted to survive in extremely dry environments. They have various adaptations to conserve water.

4. **Analyzing Each Option**:
- **Perennial non-succulent xerophytes**: These plants have extensive root systems that can penetrate deep into the soil to access subsoil water. They are well-adapted to dry conditions.
- **Perennial succulent xerophytes**: These plants store water in their tissues and typically do not have deep roots as their adaptation is more focused on water storage rather than deep penetration.
- **Annual xerophytes**: These plants complete their life cycle in one year and generally have shallower root systems as they do not need to access deep water sources for long periods.
- **Epiphytomal xerophytes**: These plants grow on other plants and do not typically have deep roots, as they rely on their host for moisture and nutrients.

5. **Conclusion**: Based on the analysis, the correct answer is **perennial non-succulent xerophytes**. These plants have deep roots that allow them to survive in arid conditions by reaching deeper water sources.
